FIELDING L. KIRTLEY, OF OLEBURNE, TEXAS.

IMPROVEMENT IN CAR-BRAKES.

Specification forming part of Letters Patent No. 164,007, dated June 1,1875; application filed April 14, 1875.

CASE A.

To all whom it may concern:

Be it known that I, FIELDING L. KIRTLEY, of Oleburne, in the county ofJohnson and State of Texas, have invented a new and Improved Automat-icOar-Brake, and I do here by declare that 'the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, forming a part of this specification, in which-Figure 1 is a bottom-plan view; Fig. 2, a longitudinal sectionalelevation; Fig. 3, a vertical cross-section.

The invention relates to car-brakes that work automatically and withoutmanual intervention as soon as thelocomotive is stopped. It consists inconnecting the brake-lever with a movable draw-bar or central buffer, sothat as soon as the engine slows up the said buffer or draw -bar isforced back by contact with that of the next adjacent car, and thebrakeshoes applied to the wheels. The buffer is jointed, so that when itis desired to back the cars the brakes may not be applied, but remainaloof from the wheels.

A represents a car truck, provided with a draw-bar or buffer, B, slottedat b to slide on the bolts 0 O, and at 12 to receive the brakelever D,which is connected, by lateral perforated ears (I and hook-rods E E,with the brake-bars F F. The buffer B has a shoulder, If, to limit itswithdrawing movement, and is jointed at 11 so that the end B maybeturned up when it is desired to back or not actuate the brakes.

I am aware that brake mechanism has been connected with buffers at eachside of car, so as to operate the brakes when the cars come together;but these are much more inconvenient, and will apply the brakes on acurve, which is not desirable.

With my invention any preferred kind of coupler may be employed, whilethe momentum of the cars will always be at once taken up by.

friction as soon as the locomotive slows up.

The draw-bar may be locked and prevented from sliding to operate thelrrakes by the insertion of a pin, G, having a projection, g, throughthe front of its slot.

I am aware that it is not new, broadly, to connect a sliding bumper witha car-brake, for the purpose of actuating the same by the momentum of athe cars.

Having thus described my invention, what I claim as new is 1. Thecombination of sliding draw-bar B, lever D, rods E E, and thebrake-bars, as and for the purpose set forth.

2. In combination with a car-brake, the sliding draw-bar B, having thejointed turn-up end B, as and for the purpose set forth.
